How To Install Webmin on Ubuntu 16.04

http://idroot.net/linux/install-webmin-ubuntu-16-04/

First, we need to add the Webmin repository so that we can easily install and update Webmin using our package manager. We do this by adding the repository to the /etc/apt/sources.list file.

Open the file in your editor:

• sudo nano /etc/apt/sources.list

Then add this line to the bottom of the file to add the new repository:

 . . . 
deb http://download.webmin.com/download/repository sarge contrib

Save the file and exit the editor.

Next, add the Webmin PGP key so that your system will trust the new repository:

• wget http://www.webmin.com/jcameron-key.asc
• sudo apt-key add jcameron-key.asc

Next, update the list of packages to include the Webmin repository:

• sudo apt update

Then install Webmin:

• sudo apt install webmin

Once the installation finishes, you’ll be presented with the following output:

Webmin install complete. You can now login to 
https://your_server_ip:10000 as root with your 
root password, or as any user who can use `sudo`.

Now, let’s secure access to Webmin by putting it behind the Apache web server and adding a valid TLS/SSL certificate.
